The EU leaders’ summit to mark the 60th anniversary of Rome agreements signing, which eventually led to the creation of the European Union, took place in Rome on March 25. This anniversary makes one think of what the EU has achieved over the years. In my opinion, the main result is that Europe has not lost its role as one of the main players in the world politics. In addition, the Euro has become the second-important currency in the world. This is certainly a great success. The fact that for many years there are no internal borders in the Western Europe is also a huge achievement. In general, I believe that the experience of the EU can be a good example for creating the future structure of the world. But I would also like to pay more attention to a number of serious mistakes that prevented the triumph of the united Europe.
